Design of Multi-Band Filters Using Parallel Connected Topology [PDF]

Radioengineering, 2018
This paper presents the design of multi-band filters using parallel connected topology. The resonator in each branch is the dual-mode resonator which provides two resonant modes per passband for miniaturization.

A Novel Filtering Power Divider Based on Ring Resonator

International Journal of Antennas and Propagation, 2022
In this paper, a compact dual-band filtering power divider (FPD) combined by conventional Wilkinson power divider and dual-mode resonators is proposed. The resonators submitting the quarter wavelength transmission line can act as a filter.
